What are the signs of poor sleep quality?

You sleep for seven or eight hours, but you still wake up exhausted, groggy, or mentally drained. During the day, you may struggle with brain fog, irritability, low motivation, or constant fatigue. If this sounds familiar, poor sleep quality could be the reason.

Understanding the signs of poor sleep quality early can help you improve recovery, boost energy naturally, and protect your overall health.
